conda 更换python版本

由 夙愿已清 提交于 2021-01-24 09:56:14
如将Anaconda 中默认版本Python3.7 版本修改成3.5 执行下列命令即可 conda install python=3.7.4 自动会卸载之前的版本，更新新的版本。 不过换了版本以后，第三方库也都需要重新安装，比如opencv，torch 其中TensorFlow 1.15版本需要单独下载，不支持，python3.8版本 下载网址： https://pypi.org/project/tensorflow/1.15.0/#files 感谢： https://blog.csdn.net/qq_31904559/article/details/84309756 来源： oschina 链接： https://my.oschina.net/u/4391345/blog/4921930

How to detect and align tilted images after cropping

由 戏子无情 提交于 2021-01-24 09:46:25
问题 I have implemented a cropping algorithm on my solution that works pretty good. The problem is when the image is tilted, the crop will work but it will have background space showing as the images will show. Cropping flow: First step: Second step: Final result: I have searched/tried multiple solutions but could not get a decent result or I'm not thinking the right way. The expected result is this: EDIT [FINAL RESULT]: import cv2 import numpy as np def order_corner_points(corners): # Separate

Get boundary from canny edges and remove the background of an image

由 荒凉一梦 提交于 2021-01-24 02:46:25
问题 I'm trying to remove the background of an image that im trying to train a neural network with. I've had little luck using the method described here (How do I remove the background from this kind of image?), but I have been able to use the Canny Edge Detector to get a semi-good "boundary" of the object in my image. Heres my code I'm running import cv2 as cv, sys, numpy as np, PIL.Image, matplotlib.pylab as plt # read command-line arguments filename = '/Users/colew/Desktop/Good_Cups_Frames

有关魔兽世界怀旧服的钓鱼工具的一点思考

由 ぐ巨炮叔叔 提交于 2021-01-22 12:27:18
手动钓鱼是真的累,思考了很久包括在网上也参考了很多思路. 抓包改协议肯定会被封,只能做物理上的自动钓鱼工具. 具体流程应该是这样 1.甩杆,计时开始 2.截图分析浮标的坐标 3.等到音频波动(鱼上钩的声音) 4.将鼠标移动到指定坐标,右击浮标,上鱼 照这个思路实现成功率50%左右的一个工具. openCV的识别能做到80%-90%左右的图像识别准确率 最主要问题是浮标距离会导致鱼上钩声音大小不同,离得近,上钩声音大,远的话,声音会较小. ##2019/10/23 主要用到库uiautomation 这个库是python用来做windows应用的自动化的。 这个库支持大部分的windows应用，不支持DirectUI程序。 很多DirectUI程序都没有实现UIAutomation Provider，所以不支持自动化，要想支持自动化，必须程序作者修改源码支持。 应用内的编辑及点击，都可以通过这个库来实现。不需要去整什么按键精灵。 automation.py 可以查看当前所有的windows应用信息 如下这段代码，可以激活你的windows应用，并在对应的坐标（x,y）右击操作。 import uiautomation as autotool def myAppClick(): detailWindow = autotool.WindowControl(searchDepth= 1,
